Adding external SMB storage does not work after update to 17

Hi, I have this weird behaviour that I can’t add new external SMB mounts. The existing SMB mounts are still working. When I add a new one I only get a red exclamation_mark and can’t save the configuration. This is also the case when I copy the configuration of an existing mounting point. This behaviour occurred after the upgrade to 17.01. I can’t see any relevant log information (apache, php…) Is this a bug in 17?
